Abstract

The utility model relates to a combination support with a sliding beam; a sliding beam is arranged under a top beam, the sliding beam is hung under the top beam through a movable suspension device; the lower part of the sliding beam is articulated with a plurality of front struts; the rear strut is composed of a hydraulic cylinder and is articulated under the rear part of the top beam through a gemel. A pushing cylinder for the sliding beam can be additionally arranged between the sliding beam and the top beam. With the utility model, the sliding beam can move forward along the top beam according to the technical requirement when being pushed manually or pushed by the pushing cylinder of the sliding beam when the position of the top beam of the combination support remains unchanged, and thus the space between the working face and the pedestrian passageway can be adjusted reasonably. The utility model is suitable for the stope face in the coal mine.

Description

The sectional shelf-unit of band sliding beam
Technical field
The utility model relates to a kind of support apparatus that uses at the underground mining work plane, particularly a kind of traversing carriage that is used for stope under the coal mine.
Background technology
In the prior art, the forward and backward pillar of sectional shelf-unit all is to be fixed on the back timber, can not move forward alone at present, and this just causes the walkway of work plane and operating space is nonadjustable defective.
The utility model content
In order to overcome the nonadjustable deficiency of forward and backward pillar fixed-site of existing sectional shelf-unit, the utility model provides a kind of sectional shelf-unit with sliding beam, the pillar of this sectional shelf-unit can be by the requirement of down-hole coal excavation technology, under the constant situation of the back timber original position of sectional shelf-unit, make the pillar reach, reasonably to adjust the space of work plane and walkway.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
A kind of sectional shelf-unit with sliding beam comprises back timber, back prop and front standing pillar, and back timber places the upper end of front standing pillar and back prop.Be provided with a sliding beam below back timber, this sliding beam is hung below back timber by erecting by overhang movably, is connected with some front standing pillars by articulated manner below sliding beam.
Can be equipped with a sliding beam propulsion cylinder below back timber, the front end and the sliding beam of this sliding beam propulsion cylinder are hinged, and rear end and back timber are hinged.
Because the utility model is provided with sliding beam, this sliding beam is hung below back timber by erecting by overhang movably, when artificial promotion or under the effect of sliding beam propulsion cylinder, sliding beam is moved forward along back timber, driving the front standing pillar that is connected the sliding beam below simultaneously moves forward, thereby can as required under back timber invariant position situation, rationally adjust the space of work plane and walkway.
The beneficial effects of the utility model are:
1, can press operation technological requirement, rationally adjust the space of work plane and walkway.
2, compliance is strong, and speed of advancement is fast, and is simple in structure.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, Fig. 2, Figure 3 shows that first embodiment of the sectional shelf-unit of the utility model band sliding beam, the back timber 1 of this sectional shelf-unit is to be framework with the i iron, and weldering one top board constitutes above.Be equipped with a joist 3 in back timber 1 lower end, joist body 8 and back joist body 9 before this joist 3 comprises are connected with a connecting rod 10 between preceding joist body 8 and back joist body 9.Joist 3 can be to front slide below back timber 1.Some back prop 4 is made up of hydraulic cylinder, is hinged on back timber 1 lower rear with hinge.Below back timber 1, be provided with a sliding beam 2, two vertical settings in long limit of this sliding beam 2 and back timber 1.Sliding beam 2 is rectangular box structural members, hangs below back timber 1 by erecting by overhang movably, just hangs on the lower edge of i iron, and can pass forward along it.Below sliding beam 2, be connected with 1,2 or 3 front standing pillars 5 by articulated manner.In the present embodiment 2 front standing pillars 5.
Erecting by overhang in the utility model can be the roller 6 of rolling friction shown in Figure 1, also can be the sliding friction erecting by overhang of roller-less.
Figure 4 shows that second embodiment of the present utility model, this sectional shelf-unit with a hydraulic cylinder as motive force.Be equipped with a sliding beam propulsion cylinder 7 below back timber 1, this sliding beam propulsion cylinder 7 is a hydraulic cylinder, and its front end and sliding beam 2 are hinged, and the top board of rear end and back timber 1 is hinged.Utilize the thrust of this hydraulic cylinder to make sliding beam 2 reaches, other structure of second embodiment is identical with embodiment one.
When work plane used, the working method and the operating procedure of the sectional shelf-unit of the utility model band sliding beam were as follows:
1, shown in Fig. 5 A, two front standing pillar 5 epicoele fluid injections are upwards mentioned two front standing pillars 5 at first forward, and it is hung below sliding beam 2.
2, shown in Fig. 5 B, promote sliding beam 2 forward, at this moment, be with front standing pillar 5 to move forward a step pitch together because the sliding beam 2 below roller is hung in the rotation of erecting by overhang roller 6.
3, shown in Fig. 5 C, load to front standing pillar 5 cavity of resorption fluid injections, make its downward elongation, the bottom is stood on the base plate.Thereby changed the working space between front standing pillar 5 and the back prop 4.
